David Rosenberg will light up his suit with pedal power on the plinth
A man pedalling a pink cycle and a woman celebrating her birthday are among those chosen to stand on Trafalgar Square's Fourth Plinth.
July's 615 "living statues" were chosen from more than 13,000 applicants who wanted to be part of artist Antony Gormley's One and Other project.
Each participant will get an hour on the plinth from 6 July.
Living statues for following months will be announced later, with 2,400 people taking part up to 14 October.
David Rosenberg, 41, a designer from London, plans to be on the plinth at night and in the one hour there he will pedal his folding pink bicycle to generate the energy to light up a specially created suit he will be wearing.
The oldest among July's 615 participants, pensioner Gwynneth Pedler, 83, from Oxford, plans to signal with semaphore flags.
Anthony Pressley, 48, a hospital porter from Worksop, will have a large cut-out photograph of his father who died when Mr Pressley was a child.
He said: "I want to make it an almost statue of the ordinary man. Not a king. Not a general, just an ordinary man. Also, it would please my family".
Heather Pringle, a student from Hexham, will celebrate her 20th birthday on the plinth.
She said: "I plan to celebrate in style, a good old fashioned birthday party. There will be cake".
The participants are chosen at random by a computer and can do anything they want on the plinth as long as it is legal.
The results for living statues for August will be chosen on 1 July. Applications will be accepted until 1 September when the last group of people are chosen.
On Thursday Westminster Council granted planning permission for Gormley's project.
